It seems wrong to ask you to "find x and y" for a single equation; is that what the problem actually said? It is important to quote the entire problem exactly (or translate it carefully, if it is in Lithuanian).

I would expand the left side (eliminate parentheses) and solve for y (which will require completing the square or using the quadratic formula). Then I might initially try to graph it. But what you will find is that y is a real number for only one value of x, which makes the question suddenly make sense. It actually has an answer.

Thank you for your answer. I study maths in Lithuanian, so I don't see English exercises often. It was written in Lithuanian. I can translate the task from LT to EN. It sound like that "Which what x and y values this is a correct equality?"

So what you're saying is that I should make a "function" (That is how we call it in LT, I don't know how it is called in English).I find what y is equal to, then I choose 2 or more y's and calculate the x's. Then I make a graph and see where it intersects. I seem to get the concept, but I get stuck at trying to solve for y. I can't part x from y. Even if I get that "y=..." in that "..." there is y too, and it also looks really wrong.

My point was not that the question was written badly, but that it is surprising! Normally one would not solve one equation for both variables, but in this case it can be done, as you discover when you do the work of trying to graph the equation (as Khan implied and I stated explicitly).
